Preparation of breathable hydrophilic membrane for fabric from mixture of polyester polyurethane copolymer and acrylate copolymer

摘要

Hydrophilic membrane containing at least one acrylate copolymer and polyester polyurethane copolymer A method for preparing hydrophilic membranes from a prepared slurry by coating on a non viscous medium or paper. Preferably, the surface of the non adhesive carrier on which the surface is to be paved to form a film,It should not contain groups that can react with functional groups in the slurry. This is to prevent degradation of the membrane after cooking and to facilitate separation of the membrane from the non adhesive medium. The advantages of the hydrophilic membrane invented by ams1 are as follows: the hydrophilic membrane can be manufactured by conventional coating system; the manufacturing cost is reasonable; the hydrophilic membrane is easy to manufacture;Maintain respiratory characteristics after washing;It is different from the damaged microporous membrane after washing;Maintain respiratory characteristics and water resistance after moderate stretching;Improve the water vapor emission kinetics after membrane saturation;Make other textile media easy to roll film composition; · obtain windproof performance.
